No HDR capability? UE50NU7022KXXH connected to the nVidia GTX 980 on my PC?

I have a UE50NU7022KXXH connected to the nVidia GTX 980 on my PC. Both pieces of hardware support HDR according to all research i have conducted. They are connected with a Club3D DisplayPort 1.4 to HDMI 2.0 Active adapter and a 4K HDMI 2.0 PS4 HDMI Cable. Windows 10 Home (64 bit) is fully updated as are nVidia drivers (Version 417.35 - 12/12/2018).
